The $y$ $y$ -intercept is at $(0, 6)$ $(0, 6)$ .

$4 x - 3 y = - 18$ $4x - 3y = -18$

To find the $y$ $y$ -intercept, plug in $0$ $0$ for $x$ $x$ and solve for $y$ $y$ :
$4 (0) - 3 y = - 18$ $4(0) - 3y = -18$

$0 - 3 y = - 18$ $0 - 3y = -18$

$- 3 y = - 18$ $-3y = -18$

Divide both sides by $- 3$ $color(blue)(-3)$ :
$\frac{- 3 y}{- 3} = \frac{- 18}{- 3}$ $(-3y)/color(blue)(-3) = (-18)/color(blue)(-3)$

$y = 6$ $y = 6$

Therefore, the $y$ $y$ -intercept is at $(0, 6)$ $(0, 6)$ .

Hope this helps!
